Many years ago Google came out with a way to let average people with a website earn rom the traffic on their site.
You placed a small code on your website from Google and now ads would appear. When these ads were clicked by people then you could make money.
The only problem with all this, is you had to have a TON and I mean a TON of traffic or visitors to your website. Without a lot of traffic you would make cents and not dollars.
So to answer your question NO Adsense is not a good way to earn for the average person.
Now don’t get me wrong, I didn’t say it was a crappy program.
If you have a lot of traffic to your website then Adsense could be a good option. Its very easy to get the code and place it on your site. So it does not require too much technical skills
But I always tell people to find others ways to earn from your website. Collect emails and send out offers. Or place banners from from people who have niche specific products.
There are just so many other ways to earn from your traffic than Adsense.
But try it out, see how it works. If its not working you can always change.
